This past May, Microsoft, including Windows Live and Bing, had around 26.2 million unique users which was a slight decrease since late last year. Facebook on the other hand has increased its users to 26.8 million which is up up 7%. This is the first time Facebook has passed up Microsoft's web dominion in the UK. Facebook has an unconfirmed 750 million users globally even though its American user base has actually decreased slightly in recent months.
Both Microsoft and Facebook pale in comparison with Google, which saw 33.8 million unique visits in May. Rival social networking site Twitter saw a huge increase in its following this past May and is up to 6 million. This is a huge 34% increase of the previous month. The growth in audiences for social networks is now primarily being driven by the 50 plus age group.
